The locomotion of a wide class of motile bacteria can be mathematically described as a biased random walk in three-dimensional space. Fluid mechanics and probability theory are invoked to model the dynamics of bacteria ...

It was the earliest of times, it was the latest of times, it was the age of inflation, it was the age of collapse, it was the epoch of perturbation growth, it was the epoch of perturbation damping, it was the CMB of light, ...

The detection of gravitational waves (GWs) from astrophysical sources shows promise as a new method to probe extremely energetic phenomena and test the strong field limit of the general theory of relativity. The era of the ...

In conventional superconductors the superconducting gap in the electronic excitation spectrum prevents scattering of low energy electrons. In high temperature superconductors (HTS) an additional gap, the pseudogap, develops ...

We develop method to extract elemental abundance ratios using temperature-insensitive ratios of x-ray line fluxes for a collisionally ionized plasma. This method is then refined using more realistic plasma models for coronae ...

In my thesis project, I provide a description of the entire process of materials preparation, assembly, testing, and characterization of several triple-GEM (Gas-Electron Multiplier) prototype detectors. GEM detectors ...

We propose a new method to detect intergalactic Lyman a emitter and absorber systems by comparing broadband and narrowband images. The narrowband observations were carried out with the Maryland-Magellan Tunable Filter ...

The relation between processing, microstructure, and material property was investigated in the high-temperature superconducting Bi₂Sr₂Ca₁Cu₂Ox̳/Ag system. Experiments were based on a theoretical surface energy model ...
